2012年ISO TC 131/SC6 国际流体污染控制标准化会议

2012年ISO TC 131/SC6 国际流体污染控制标准化会议于 2012年5月21日在河南省新乡市的国际饭店举行,本次会议为期三天,是国际最权威的流体污染控制专业技术会议,参加会议的有国际标准化组织ISO/TC131/SC6(国际标准化组织流体传动技术委员会污染控制分会)主席、秘书处成员和来自美国、英国、法国、德国、意大利、中国等国家的流体污染控制领域的30余位专家。

IFTS总经理Christophe PEUCHOT作为ISO/CD 18413的Project Leader,就各国代表团针对该标准提出的建议意见逐一进行解释并与标委会各代表进行沟通。IFTS在液体中杂质颗粒控制,自动颗粒计数方面有丰富的经验。

IFTS 对法国、欧洲和世界的标准化及认证活动的贡献

I – 介绍

  IFTS是一个非盈利性质,自筹资金的技术研究中心。由于其作为介于大学研究中心和滤清器设备制造商和用户之间的接口,IFTS承担了旨在改善该领域相关专业知识的相互理解和交流沟通的活动。

  此外,鉴于IFTS胜任多工业领域的工作,IFTS覆盖的工业系统从化工到机械,核电到航空航天,食品到环境。1986年我们研究所创建4个具体的活动以提供有效的工具,为行业提供更大的工业竞争力。这主要包括研究和开发测试方法,试验台架,标准化,依据ISO 17025对实验室进行认可,对过滤产品进行认证。

  本文描述了本研究中心在国家和国际标准水平下作的规范工作。

  同时包括参与多用户研究和组织或参与全球比对测试。这些也都被用于标准和操作方法正式发布前的验证。

IFTS's Contribution to French, European and International Activities of Standardisation and Certification

I – INTRODUCTION

IFTS is a Technical Research Centre, an association which is non-profit making and selffinanced. Because it operates as an interface between university research and filter equipment manufacturers/users, IFTS undertakes activities which help to improve understanding and communication between these fields of expertise.

Furthermore, because of its multi-industry competence, IFTS covers a wide range of industrial systems from chemical to mechanical, nuclear to aeronautical, food to environment in 1986 the Institute started four specific activities to make available to industry efficient tools for greater industrial competitivity. These are the research and development of test methods and equipments, standardisation, certification of its services according to ISO 17025, and certification of filtration products.

This document describes normative and paranormative work undertaken by the Institute at national and international levels.

Also included is a summary of the involvement in multiclient research and round robin tests which IFTS has organised or in which it has participated with other professionals. This is undertaken to validate standards and operating protocols before they are published.

ISO/TR 13353(1994)标准已不再有效

  近来,我们接到不少中国客户关于依据ISO/TR 13353(1994)标准对燃油滤清器进行性能测试的咨询,他们希望我们依据这个标准来进行试验。

  ISO/TR 13353(1994) 是一个旧的标准,早在2002年8月29日就已经撤销了。我们向这些客户解释:我们IFTS还有一些可用的ACFTD,我们可以将测试得到的µm(c)转换成µm,这也是我们可以使用这个旧标准做测试的原因。

  这些国内的客户说是他们的客户(即滤清器用户)要求他们使用这个标准进行燃滤性能测试。

  本文将介绍这个燃油滤清器性能测试标准的升级。以期帮助广大滤清器用户和滤清器制造商了解这个标准的背景。

  在1994年,IFTS创建起草了ISO TR 13353标准用来评估燃油滤清器的过滤效率和容灰量,BOSCH接受并使用了该标准。ISO TR 13353 (1994) 分为两个部分:第一部分是用于评估滤清器的初始效率(单次通过循环,5mg/L 的ACFTD ——过滤效率表述为多少µm的粒子效率是多少;第二部分是用于评估滤清器的容灰量(多次通过循环,50mg/L 的ACFTD,终止条件为压差上升70kPa)

  自从1999年起,ACFTD已经不再生产;被ISO MTD取代。而且颗粒计数器的标定标准也由ISO 4402(1991)升级到了ISO 11171(1999)。延伸阅读:试验粉尘的历史(英文版中文版);

  ISO/TS 13353(2002)是作为评估初始效率的标准而被重新审核评估的(使用上游杂质浓度 5mg/L 的ISO MTD,单次通过——过滤效率表述为多少µm (c)的粒子的过滤效率是多少。

ISO 19438 (03)被用于评估滤清器的效率和容灰量的评估,使用的是50mg/L ISO MTD,使用在线稀释系统便于颗粒计数——过滤效率表述为多少µm (c)的粒子的过滤效率是多少。

  也就是说,现如今,ISO/TR 13353(1994) 已经无效,被ISO 19438(2003)所取代。

  于2004年进行的全球比对试验证明了在初始效率测试方面,使用ISO TS 13353 (02) 或 ISO 19438 (03)获得的结果是相似的。通常来说,包括BOSCH在内的燃油滤清器用户(或发动机主机厂)应该已经有了接受ISO 19438的规范。

  上述所有的标准替代,您均可通过在ISO官方网站上查询标准号来找到替换记录,比如下图中用红色圈出的部分显示了ISO/TS 13353(2002)曾替代了ISO/TR 13353(1994),并被ISO 19438(2003)替代。

关于新旧颗粒尺寸读取及转换,我们推荐您购买ISO/TR 16386(1999)阅读了解。

ISO/TR 13353:1994 is no longer available

Recently, we have got some inquires for fuel filter testing according to ISO/TR 13353(1994) from the customers in China, they asked us to run test for them according to this standard.

 
ISO/TR 13353(1994) is an old test standard which has already been withdrew on August 29th of 2002. We explained that we have some more ACFTD available by IFTS and we can correlate from µm(c) to µm. That is the reason why we can work according to this old standard.
 
These Chinese customer told us their customers (the filter end users) ask them to use this standard to test the fuel filter.
 
This article introduces the upgrading of this testing standard for diesel fuel filters. Try to help filter users and filter manufacturers to understand the background of this testing standard.
 
 
ISO/TR 13353(1994) was founded by IFTS and accepted by BOSCH in 1994. It is in order to qualify the filtration efficiency and the retention capacity of fuel filters. This procedure is divided in two parts: a first one is dedicated with the determination of the initial filtration efficiency (singlepass circulation at 5 mg/L of ACFTD – expression of the filtration ratings in µm); The second one is dedicated with the determination of the retention capacity (multipass recirculation at 50 mg/L of ACFTD up to an increase of DP of 70 kPa).
 
Since 1999, the ACFTD no more available ; it has been replaced by ISO MTD and the calibration for the APC (automatic particle counter) has been upgraded: the ISO 4402(1991) has been revised by the ISO 11171(1999). About dust history, please read here.
 
ISO/TS 13353(2002) has been reviewed and is only dealing with the determination of the initial filtration efficiency (according to a BUGL of 5 mg/L of ISO MTD in a single pass way – expression of the filtration ratings in µm(c) ).
 
ISO 19438 (2003) has been standardised for determining both the filtration efficiency and the retention capacity with working in a multipass recirculation with a BUGL of 50 mg/L of ISO MTD and on line dilution concerning particle counting – expression of the filtration ratings in µm(c) ).
 
That is to say, nowadays, ISO/TR 13353 (1994) is no more available. Has been replaced by ISO 19438(2003).
 
Last round robin tests in 2004 have proven that the determination of the initial filtration efficiency is similar whatever using ISO/TS 13353 (2002) or ISO 19438 (2003). Normally, including BOSCH, the fuel filter users should make the specification with using ISO 19438 procedure.
 
All above standards’ upgrading, you could find records on the official ISO website. For example, you could find the revision information for ISO/TS 13353(2002) in below image, it revised ISO/TR 13353(1994) and has been revised by ISO 19438:

 

For more detailed historical background, we suggest you to refer to ISO/TR 16386(1999).
